Faculty of Science | Silicon Carbide

When oxidising silicon a silicon dioxide layer forms but in silicon carbide the extra carbon atom is either released as CO gas or it clumps together to form uneven oxides on the surface.” At very high temperatures however, the likelihood that CO gas is formed increases and it is thought that this will be a key breakthrough in developing the technique for producing a unifrom oxide layer.
